Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19376, here are decompositions:
- 3 + 19373 = 19376
- 43 + 19333 = 19376
- 67 + 19309 = 19376
- 103 + 19273 = 19376
- 109 + 19267 = 19376
- 127 + 19249 = 19376
- 139 + 19237 = 19376
- 157 + 19219 = 19376
Showing the first eight; more decompositions exist.
